      Public health risks related to communicable diseases
                        during the 2018 Hajj, Saudi Arabia,
                                        19–24 August 2018
                                                                                                              2 August 2018

      Main conclusions and options for response
      This year, the Hajj takes place between 19 and 24 August. This document assesses the potential risk of
      outbreaks/transmission of communicable diseases during the 2018 Hajj.
      Due to the vaccination requirements for travelling to Mecca, Saudi Arabia, and the preparedness plans put in
      place by the host country addressing the management of health hazards during and after the Hajj, the overall
      risk for EU/EEA citizens of becoming infected with a contagious disease during the 2018 Hajj in Saudi Arabia is
      considered to be low.
      The risk of communicable disease outbreaks is highest for food- and waterborne diseases and respiratory
      illnesses, but the risk is not considered higher than can generally be expected for international mass
      gatherings of this size. MERS-CoV activity continues to be reported in the Arabian Peninsula, specifically from
      Saudi Arabia, and therefore imported cases may be detected in Europe following the Hajj. The risk of
      transmission of other vaccine-preventable and vector-borne diseases is considered to be low.
      The national health authorities in countries from where Muslims embark on the Hajj pilgrimage to Mecca
      should apply appropriate strategies for the prevention and control of communicable diseases before, during
      and after the completion of the Hajj.

      Advice for those travelling to the Hajj
      Prior to travelling
      •      Seek advice from healthcare providers on vaccination visa and entry requirements for Saudi Arabia;
             follow recommendations issued by the ministry of health of Saudi Arabia [33] and WHO [64].
      •      Ensure you are up to date with routine vaccinations, including boosters as recommended in your EU
             country of residence. See ECDC vaccine schedule site [65].

      During the Hajj
      •      Pay attention to personal, food and water hygiene to decrease the risk of gastrointestinal illnesses.
      •      Practise respiratory hygiene and cough etiquette to reduce the risk of respiratory infections.
      •      Visit only licensed barbers for shaving.

RAPID RISK ASSESSMENT Public health risks related to communicable diseases during the 2018 Hajj – 2 Aug 2018

  •      Avoid close contact with animals, particularly camels, when visiting farms, markets, or barn areas.
  •      Only use antibiotics according to the advice of a certified health professional.

  After the Hajj
  •      If you have symptoms suggestive of gastrointestinal, respiratory or any other type of infection upon
         return, make sure you mention your travel history to your healthcare provider.
  •      Due to the continuing reports of MERS-CoV disease in Saudi Arabia, seek immediate medical advice if
         you have a fever (38 ºC and over), cough or difficulty in breathing.
  •      Report your travel history and previous hospitalisation to your healthcare provider if you require
         hospitalisation within one year of travel to another country (or if hospitalised in another country), to
         ensure that the possible acquisition of antimicrobial-resistant (AMR) bacteria is considered and that
         appropriate measures can be implemented in accordance with national guidelines to prevent the spread
         of AMR.
  Based on the general risks during mass gathering events, and in accordance with the internal procedures
  applied for those events, ECDC will conduct enhanced epidemic intelligence surveillance for communicable
  diseases between 12 and 31 August 2018.

Event background information
More than one and a half million pilgrims from all over the world travel every year to Saudi Arabia for the Hajj. In
August 2017, 1 752 014 foreign and 600 108 domestic pilgrims took the Hajj. In 2017, most of the foreign pilgrims
arrived by air (94%), while only five percent crossed the land border; one per cent came by sea [1].
In 2016, the Hajj took place between 10 and 15 September, resulting in an increase in travel patterns from the
EU/EEA during the month preceding the Hajj (Figure 1). According to IATA data, in August and September 2016,
more than 200 000 travellers from EU/EEA countries travelled to Saudi Arabia. The majority of the travellers
originated from the United Kingdom (41%), Germany (14%) and France (13%).

RAPID RISK ASSESSMENT Public health risks related to communicable diseases during the 2018 Hajj – 2 Aug 2018

Risk for importation of communicable diseases to the Hajj
The risk of importation of communicable disease to Saudi Arabia by pilgrims participating to the Hajj relates to
ongoing endemic infections and outbreaks in the country of origin of pilgrims.
The following outbreaks should be considered of relevance:
•      Cholera outbreaks are currently occurring in many countries especially in the Horn of Africa and the Gulf of
       Aden, including Yemen, Somalia, and Ethiopia. Outbreaks are also reported in the Democratic Republic of
       the Congo, Kenya, Tanzania and Nigeria [2,3].

Map 1. Geographical distribution of cholera cases detected worldwide in the past six months, as of 18
July 2018

•      As of 3 July 2018, Poliomyelitis, with wild poliovirus cases has been reported in Afghanistan (eight cases)
       and Pakistan (three cases). Circulating vaccine-derived poliovirus type 2 was reported in: Nigeria (one
       case), the Democratic Republic of Congo (seven cases), Somalia (four cases: circulating vaccine-derived
       poliovirus type 2 and 3); circulating vaccine-derived poliovirus type 1 was identified in Papua New Guinea
       (one case) [4]. Although Nigeria has not reported cases of wild poliovirus in the last two years, it is still
       regarded as an endemic country [5].
•      Yellow fever, chikungunya, and dengue are associated with ongoing outbreaks in many countries. This
       increases the possibility of the introduction of these viruses through viraemic travelers [6,7]. ECDC monitors
       these global outbreaks through open source event-based surveillance; the list of countries below may not
       be exhaustive.
       Dengue is endemic in many countries and has been reported in over 128 countries [8]. Reporting of
       arbovirus infections can differ across countries in relation of their surveillance system. It should be noted
       that underreporting of arboviruses is considered to occur in sub-Saharan Africa.
       Yellow fever is endemic in tropical and subtropical areas of Africa and Central and South America (including
       Trinidad) [9]. Between 12 September 2017 and 3 June 2018, 1 903 suspected yellow fever cases, including
       47 deaths, were reported in Nigeria [10]. Between July 2017 and week 19-2018, the ministry of health in
       Brazil reported 1 266 confirmed human cases of yellow fever, including 415 deaths [11].
       Dengue is found in tropical and subtropical climates worldwide, mostly in urban and semi-urban areas [12].
       Cases of dengue have recently been reported in the Americas, south-east Asia and the Pacific Island
       nations [13].

Map 2. Geographical distribution of dengue cases detected worldwide in the past six months, as of
18 July 2018

•     Chikungunya mostly occurs in Africa, Asia and the Indian subcontinent, in tropical and subtropical areas
      where Aedes aegypti and Aedes albopictus is found. Chikungunya virus has become a frequent cause of
      travel-associated febrile illness, and returning viraemic travellers can be the source of autochthonous
      transmission in areas suitable for arbovirus transmission [14].
Map 3. Geographical distribution of Chikungunya cases detected worldwide in the past six months, as
of 18 July 2018

•     Seasonal influenza: currently circulating in the southern hemisphere and tropical and subtropical areas
      countries [15].
•     Measles: outbreaks are ongoing in Europe, Africa, Americas and Asia. [16,10].
•     Meningococcal disease: according to enhanced surveillance from 23 countries, a total of 29 827 suspected
      meningitis cases (including 2 276 deaths) was reported in 2017 [17]. This represents an increased number
      of cases compared with 2016 when there were 18 178 suspected cases. The highest rates of meningitis are
      reported from the extended meningitis belt of sub-Saharan Africa, stretching from Senegal in the west to
      Ethiopia in the east, covering 26 countries. According to a recent study, the meningococcal carriage among
      Hajj pilgrims ranged from 0 to 27% (2007–2016), with serogroup B being the most prevalent [18]. An
      outbreak of serogroup W-135 meningococcal disease occurred during the 2000 Hajj; of the 253 cases
      identified in Saudi Arabia, 161 (64%) had serogroup identification [19].
•     Lassa fever is known to be endemic in Benin, Ghana, Guinea, Liberia, Mali, Sierra Leone, and Nigeria.
      Sporadic cases can also be detected in other West African countries [20]. In 2018, Nigeria reported 2 042

RAPID RISK ASSESSMENT Public health risks related to communicable diseases during the 2018 Hajj – 2 Aug 2018

       cases, 444 of which were confirmed [10]. In 2018, Liberia reported 20 confirmed cases out of 123
       suspected cases; of these confirmed cases, 13 deaths were reported. Sierra Leone reported 16 confirmed
       cases, including six deaths.
•      Crimean Congo haemorrhagic fever (CCHF) is endemic in countries in the Eastern Mediterranean Region of
       WHO, including Iran, Iraq, Kuwait, Oman, Pakistan, Saudi Arabia, Sudan and the United Arab Emirates [21].
       In 2018, an upsurge of CCHF cases has been reported in Afghanistan with 125 cases, including 18 deaths
       [10]. As of 7 July, Iraq reported eight cases, including six deaths in 2018 [22]. According to media reports,
       Iran experienced 34 cases (including three deaths) between April and June 2018 [23]. In Turkey, CCHF
       cases are reported on an annual basis: in 2016, 432 cases were notified; in 2017, 343 cases (including 16
       deaths) were reported [24]. According to media quoting national authorities, around 300 cases are
       expected for 2018 [25]. In 2018, Russia reported 62 cases between January and June. In 2016 and 2017,
       162 and 79 cases, respectively, were reported for the year [26].
•      Diphtheria: According to WHO, a diphtheria outbreak in Yemen that began in 2017 has reached 1 904
       suspected cases, including 98 deaths, as of 8 July 2018. An outbreak is also ongoing in Bangladesh, with
       7 888 suspected cases, including 55 deaths [27]. In the Region of the Americas in 2018, three countries –
       Colombia, Haiti and the Venezuela – reported diphtheria cases, compared with four countries (Brazil, the
       Dominican Republic, Haiti and Venezuela) in 2017 [28].

Risk of transmission during the Hajj
The risk of local transmission of communicable diseases during the Hajj is increased in places of pilgrimage
because of overcrowding, the presence of at-risk populations such as elderly and polymorbid participants, and the
possible breaches of food-hygiene standards.

Meningococcal diseases
The transmission of meningococcal meningitis is facilitated by crowded environments [29]; transmission has
occasionally occurred during the Hajj.
The risk of importation of meningococcal meningitis is increased during the seasonal peaks in the countries of the
African meningitis belt, several of which are home to large Muslim populations.

Food- and waterborne diseases
Gastrointestinal illnesses during mass gathering events, including the Hajj, are a possible health threat. This is due
to possible breaches of food hygiene standards, shortage of clean water, the presence of mildly ill and
asymptomatic carriers of pathogenic bacteria and viruses, and the preparation of large numbers of meals that may
be inappropriately stored by pilgrims. There are several studies describing the incidence and aetiology of traveller’s
diarrhoea during the Hajj [30-32].
Hajj pilgrims are not allowed to bring fresh food into Saudi Arabia. Only properly canned or sealed food or food
stored in containers with easy access for inspection is allowed in small quantities, sufficient for one person for the
duration of the trip [33].

Malaria
Malaria is a widespread parasitic disease in tropical areas, and it is likely that a significant number of pilgrims host
the parasite. Outbreaks of malaria have occurred during the Hajj in the past [34].
Saudi Arabia is currently at the pre-elimination phase of malaria, and local transmission of malaria has only been
reported in villages along the border with Yemen [35,36]. Therefore, the risk of transmission in relation to the Hajj
is very low.

Arboviruses
Aedes aegypti mosquitoes have not been detected in areas where the Hajj is taking place. However, Ae. aegypti is
present in surrounding cities, for example Jeddah [37]. A recent literature review identified that dengue outbreaks
have regularly occurred in Saudi Arabia since the 1990s [38,39]. Therefore, there is a possibility of an outbreak
associated with arboviruses transmitted by Ae. aegypti [40].
Recent dengue cases were detected in July 2018 in Al-Taif governorate, Mecca Region [41]. On 6 July 2018,
French authorities used the EU Early Warning and Response System (EWRS) to report two DENV-3 (dengue virus
type 3) infections in two siblings returning from Saudi Arabia on 16 June 2018 after a pilgrimage to Mecca and
Medina. Both patients developed a dengue-like syndrome on 17 June.
Alkhurma haemorrhagic fever (AHF) is a tick-borne disease found in Saudi Arabia and in Egypt. In Saudi Arabia,
outbreaks have been reported from Jeddah and Mecca (see
https://www.cdc.gov/vhf/alkhurma/outbreaks/distribution-map.html). According to media reports, quoting local

                                                            6
RAPID RISK ASSESSMENT Public health risks related to communicable diseases during the 2018 Hajj – 2 Aug 2018

authorities, a recent outbreak occurred in Jeddah in April 2018 [42]. The virus is transmitted by ticks, following
contact with livestock, including sheep. The risk of AHF is probably low, but it should be considered as a differential
diagnosis for viral haemorrhagic fevers.

Tuberculosis
It is difficult to assess the transmission of tuberculosis during the Hajj due to the long incubation period. However,
based on the origin of the pilgrims, many of whom come from areas where tuberculosis is endemic, a risk for the
spread of tuberculosis exists. Contributing factors are overcrowding, and co-morbidities which make pilgrims
susceptible to infection or reactivation of latent tuberculosis. There is evidence indicating a significant risk of
getting infected during the Hajj [43].

Blood-borne pathogens
At the end of Hajj, men shave their heads. If contaminated barber blades are used, transmission of blood-borne
pathogens, such as hepatitis B, hepatitis C, and HIV cannot be excluded. At the Hajj, licensed barbers are tested
for blood-borne pathogens. They are also required to use disposable, single-use blades, while unlicensed barbers
might use nonsterile blades. Male pilgrims are advised to visit licensed barbers [44].

Risk of exportation of infectious diseases related to the Hajj
Returning pilgrims could be affected by the communicable diseases mentioned above and could thus trigger a local
chain of transmission in their home countries. For vector-borne diseases, there must be a competent, active vector
population in the home country. In studies performed among European Hajj returnees in recent years, many
pilgrims tested positive for influenza viruses [45-47].
Two conditions associated with nosocomial transmission are of particular relevance in the context of the Hajj:
infection with MERS-CoV, and infection with, or carriage of, antimicrobial-resistant bacterial strains.

Middle East respiratory syndrome
Although no cases of MERS-CoV infection have been associated with Hajj events since the discovery of the virus in
September 2012, the disease still raises concerns because of MERS outbreaks in Saudi Arabia linked to camel
contact and transmission in healthcare settings continue [48]. At the end of June 2018, 2 229 laboratory-confirmed
cases of MERS-CoV, including 791 associated deaths (case–fatality rate: 35.5%) were reported globally; the
majority of these cases were reported from Saudi Arabia: 1 853 cases (including 717 related deaths, case–fatality
rate 38.7%) [49]. Many of the primary cases reported direct camel contact or consumption of raw camel milk,
while the secondary cases mostly occurred in healthcare settings. During March 2018, a hospital outbreak was
detected in Riyadh, Saudi Arabia [50].
While camel contact is unlikely during participation in the Hajj, hospitalised pilgrims may become exposed to
MERS-CoV. Nonetheless, since MERS-CoV infection has never been reported in a Hajj pilgrim, despite intensive
surveillance among returnees, the probability of a returning pilgrim being infected with MERS-CoV is very low.
Transmission in home countries after travelling to a MERS-CoV-affected country has been documented in several
instances, e.g. in the UK [51], France [52], and South Korea [53], albeit not in the context of the Hajj. Therefore,
the probability of limited transmission in EU Member States following importation can be considered low, but not
negligible, especially in healthcare settings.

Antimicrobial resistance and healthcare-associated infections
High rates of antimicrobial resistance (AMR) in gram-negative and gram-positive bacteria [54] are reported from
the eastern Mediterranean region. Increasing resistance in gram-negative bacteria has been reported for Saudi
Arabia; this includes increases of carbapenemase-producing Enterobacteriaceae and carbapenem-resistant
Acinetobacter baumannii, as well as hospital outbreaks of multidrug-resistant bacteria (MDR bacteria) [55-57].
Over-the-counter use of antibiotics without prescription, heavy international travel due to the pilgrimage, a large
population of expatriates, and challenges with adherence to infection control measures (such as hand hygiene) in
hospitals have been identified as local risk factors contributing to the emergence of AMR [58].
A recent systematic review showed a high prevalence and/or high risk of acquisition of MDR bacteria in pilgrims
during the Hajj [59]. Factors promoting the acquisition of MDR bacteria during the Hajj include crowding; lack of
effective food, water and personal hygiene measures; and the acquisition of respiratory and gastrointestinal
infections with subsequent antimicrobial use and healthcare exposure [59]. Pilgrims who acquire MDR bacteria
abroad and return to their home countries represent a potential reservoir for onward transmission of MDR bacteria
in the community and hospitals.

RAPID RISK ASSESSMENT Public health risks related to communicable diseases during the 2018 Hajj – 2 Aug 2018

ECDC threat assessment for the EU
The Hajj is one of the world’s largest annual mass gathering events and may result in the importation and
transmission of infectious diseases related to the crowded conditions during the pilgrimage. This may contribute to
the international spread of diseases and the amplification of infectious disease outbreaks.
Despite a few outbreaks that have previously affected the EU after the Hajj, the Hajj poses a low risk for the
importation and spread of communicable disease in the EU, thanks to the strict precautionary measures taken by
Saudi Arabia.

Conclusions and options for response
ECDC monitors current outbreaks worldwide and published the results in the weekly Communicable Diseases
Threat Report [7]. In addition, ECDC steps up its epidemic intelligence activities during and after the Hajj to detect
possible events that could pose a public health threat to the EU/EEA Member States.
In the event of a public health emergency of international health concern (PHEIC), or in the case of any disease
outbreak subject to notification under the International Health Regulations 2005, the health authorities in Saudi
Arabia – following consultation with WHO – will undertake additional preventive precautions necessary to avoid the
spread of infection during and after the pilgrimage (in the pilgrim’s country of origin).

General precautions
For each Hajj season, the Saudi Arabian ministry of health publishes a list of health requirements for the Hajj that
includes vaccination requirements and recommendations (see Annex) [33].
Before the event, pilgrims should ensure that they meet the visa requirements, receive the required and
recommended vaccines, as well as routine immunisations including booster doses recommended in their home
country. The national health authorities of the countries of origin of Hajj pilgrims should have appropriate
strategies in place aimed at the prevention and control of communicable diseases before, during, and after the
completion of the Hajj. The current international collaboration in planning vaccination campaigns, developing visa
quotas, arranging rapid repatriation, and managing health hazards at the Hajj are crucial steps in this process.
Returning pilgrims should be vigilant for symptoms of acute respiratory illness with fever and cough during the first
two weeks after their return. Returning pilgrims experiencing such symptoms should seek immediate medical
attention and inform health attendants of their recent travel to Hajj in order to detect and manage the diseases
associated with those symptoms (e.g. MERS-CoV, influenza). Influenza infections occur frequently, and early
detection of influenza is important to enable the appropriate management of the disease, including antiviral
treatment, minimised contact with others, strict cough etiquette, and respiratory hygiene. Health facilities should
ensure that appropriate arrangements are in place for testing returning pilgrims who present with symptoms
suggestive of MERS-CoV.

Specific recommendations (WHO, and ministry of health
Saudi Arabia)
General public health recommendations
Prevention of respiratory illness and MERS-CoV infection. The Saudi ministry of health advises all pilgrims
to comply with public health recommendations to prevent the spread of respiratory infectious disease [33],
including the following:
•      Washing hands with soap and water or using a disinfectant, especially after coughing and sneezing, after
       using toilets, before handling and consuming food, after touching animals
•      Practise respiratory hygiene and cough etiquette to reduce the risk of respiratory infections. Using
       disposable tissues when coughing or sneezing and dispose of it in the wastebasket
•      Trying as much as possible to avoid hand contact with the eyes, nose and mouth
•      Wearing masks, especially when in crowded places
•      Avoiding direct contact with the persons who appear ill with cough, sneeze, expectoration, vomiting, or
       diarrhoea, not sharing their personal belongings, and maintaining good personal hygiene
•      Avoiding close contact with animals, particularly camels, when visiting farms, markets, or barn areas
•      Avoiding consumption of raw camel products including milk and meat that has not been properly cooked.
Prevention of food-borne infections. The most important measures to prevent gastrointestinal illnesses are to
drink safe water (chlorinate or boil water before consumption), use appropriate food hygiene, wash hands regularly
with water and soap, eat thoroughly cooked food, carefully wash fruits and vegetables with bottled or chlorinated
water before peeling and before consumption. Avoiding consumption of raw seafood products.

RAPID RISK ASSESSMENT Public health risks related to communicable diseases during the 2018 Hajj – 2 Aug 2018

Health education. Health authorities in countries of origin should provide pilgrims with information on infectious
disease symptoms, including significant changes of body temperature, modes of transmission, complications, and
means of prevention. All pilgrims should be advised to drink plenty of clean water, preferably bottled, chlorinated
or boiled and cooled, to avoid dehydration. This is particularly important for children and older pilgrims.
Consumption of salt-containing food and drink, unless contraindicated, will also be helpful.

Recommendations for specific diseases
•      Yellow fever: pilgrims arriving from countries or areas at risk of yellow fever transmission (see list in the
       Annex) and pilgrims having transited for more than 12 hours through an airport of a country with risk of
       yellow fever transmission, are required to present a valid International Certificate of Vaccination or
       Prophylaxis (ICVP) documenting yellow fever vaccination at entry in Saudi Arabia. Since July 2016, the ICVP
       for yellow fever is valid for life, starting 10 days after the vaccination date.
•      Meningococcal disease: pilgrims are required to carry a certificate of vaccination against meningococcal
       disease. Adults and children aged two years and over should be vaccinated with the tetravalent (ACYW135)
       vaccine no less than 10 days before arrival. Polysaccharide ACWY vaccine should have been administered
       no more than three years, and conjugate ACWY vaccine no more than five years, before arrival. Pilgrims
       from the meningitis belt in sub-Saharan Africa (see Annex) will receive chemoprophylaxis at their port of
       entry to lower the rate of meningococcal carriage [33,60]. Tetravalent ACWY vaccines do not protect
       against all invasive serogroups, such as MenB and MenX. While no major MenB or MenX outbreaks have
       been reported in Saudi Arabia, these serogroups have been known to have caused disease among pilgrims
       and the Saudi population and were isolated from pilgrims in carriage studies [61]. Hajj pilgrims may
       consider vaccination against MenB, although not required at port of entry, based on therapeutic indications
       of available vaccines, and on HCP assessment.
•      Poliomyelitis: pilgrims arriving from countries with circulating wild polio virus type 1 or circulating vaccine-
       derived polio virus with potential risk of international spread should provide a proof of receipt of a dose of
       oral polio vaccine (OPV), or inactivated polio vaccine (IPV), within the previous 12 months and at least four
       weeks prior to departure. They will also receive one dose of OPV at all border points on arrival in Saudi
       Arabia (see Annex).
•      Seasonal influenza: Seasonal influenza vaccination with the most recently available vaccine (2017/18
       vaccine in the northern hemisphere and 2018 vaccine in the southern hemisphere) is recommended for
       pilgrims prior to arrival [62].
•      Cholera: since 2012, the ministry of health of Saudi Arabia has instructed the public health staff at ports of
       entry to be observant of pilgrims coming from areas with ongoing cholera outbreaks. Emphasis is on early
       detection of cases and timely provision of treatment at Hajj premises once pilgrims have passed the ports of
       entry [63].
•      MERS-CoV: WHO does not recommend travel restrictions and has updated its travel recommendations for
       pilgrims [64].
•      Dengue and chikungunya virus diseases: pilgrims should practise insect bite avoidance measures. [33].
•      Malaria: the ministry of health of Saudi Arabia and WHO do not recommend malaria prevention measures,
       including chemoprophylaxis, in the cities of Mecca and Medina [33,36].
•      Measles: outbreaks continue to occur globally. There is a risk of spread and sustained transmission in
       areas with susceptible populations. It is strongly recommended that non-immune pilgrims attending the Hajj
       are vaccinated in accordance with the national schedule prior to their travel, e.g. two doses of measles-
       containing vaccine [32,33].

Recommendation for routine immunisations
The ministry of health of Saudi Arabia recommends pilgrims to be up-to-date on routine immunisations. WHO
recommendations are available for childhood and for life-long protection against diphtheria, tetanus, pertussis,
polio, hepatitis B, haemophilus influenzae type b, pneumococcal and rotavirus (infants only) infections, measles,
mumps, rubella, typhoid, yellow fever and rabies [33]. The WHO position papers also provide travel
recommendations. It is strongly recommended that non-immune pilgrims initiate, and ideally complete, their
immunisations prior to travelling and, for those who did not complete a primary course or for whom a booster is
routinely recommended, that they complete the schedule upon return to their home country.

                                                          9
RAPID RISK ASSESSMENT Public health risks related to communicable diseases during the 2018 Hajj – 2 Aug 2018

Additional ECDC recommendations
Pilgrims should only use antibiotics when prescribed by a certified health professional. They should be advised to
always follow their healthworker’s advice when using antibiotics, and not share or use leftover antibiotics.
If pilgrims require hospitalisation within one year after returning from the Hajj and/or another country (or if
hospitalised in another country), they should report their travel history and previous hospitalisations to their
healthcare provider in order to consider the possible acquisition of antimicrobial-resistant (AMR) bacteria or MERS-
CoV; this makes it possible to implement appropriate control measures in accordance with national guidelines.
Food-borne infections. The most important measures to prevent gastrointestinal illnesses are the use of adequate
sanitation, safe water (chlorinate or boil water before consumption) and appropriate food hygiene, regular hand
washing with soap, eating thoroughly cooked food, carefully washing fruits and vegetables with bottled or
chlorinated water before consumption, and avoiding consumption of raw seafood products. Another available
measure to prevent food- and waterborne diseases is vaccination against hepatitis A and typhoid fever. In the
EU/EEA, hepatitis A vaccines are available as stand-alone vaccinations or in combination with HBV antigen or
typhoid antigen. Typhoid vaccine is also available as stand-alone vaccine.

Disease/conditions of special importance during Hajj and Umrah
Yellow fever
The ministry of health in the Kingdom of Saudi Arabia requires that all travelers arriving from countries or areas at
risk of yellow fever transmission (see below) must present a valid yellow fever vaccination certificate. The yellow
fever vaccination certificate is valid for life starting 10 days after vaccination.
Countries/areas at risk of yellow fever transmission, as per the WHO International Travel and Health
guidelines, are:
•        Africa: Angola, Benin, Burkina Faso, Burundi, Cameroon, the Central African Republic, Chad, Congo, Côte
         d’Ivoire, the Democratic Republic of the Congo, Equatorial Guinea, Ethiopia, Gabon, Gambia, Ghana,
         Guinea, Guinea-Bissau, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, Sudan, the
         Republic of South Sudan, Togo, and Uganda.
•        Americas: Argentina, the Bolivarian Republic of Venezuela, Brazil, Colombia, Ecuador, French Guiana,
         Guyana, Panama, Paraguay, Peru, the Plurinational State of Bolivia, Surinam, and Trinidad and Tobago.
